A 12-year-old girl and her younger brother go on the run in the woods of northern Idaho, pursued by four men they have just watched commit murder - four men who know exactly who William and Annie are and where their desperate mother is waiting for news of her children's fate.
The kids soon find they don't know whom they can trust among their LA-transplant neighbours, including hundreds of retired Southern Californian cops who've given the area its nickname: Blue Heaven. As a group of dirty cops spearhead the search for William and Annie, one false move will stop these children from ever finding their way home.
